Efeitos do exercício físico na qualidade do sono de indivíduos com osteoartrite: uma revisão sistemática

Abstract

Osteoarthritis (OA) is the most common type of arthritis, often affecting hips, knees, feet, and hands joints. People with OA typically complain of chronic pain that leads to discomfort at night and sleep disturbances. Studies suggest positive effects of physical exercise on pain levels, sleep quality, depression, quality of life, psychological stress, sleep disturbance, and physical function in individuals with OA. Individuals who exercise regularly have reduced cortisol, which can influence sleep quality. This systematic review aimed to summarize the scientific evidence on the effect of physical exercise on the sleep quality of OA individuals. This study followed the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA) statement and was registered in International Prospective Registry of Systematic Reviews (PROSPERO) (CRD42022316819). The PEDro Scale evaluated the methodological quality and RoB 2 the risk of bias. Seven databases (MEDLINE/PubMed; PEDro; CINAHL; Scopus; Web of Science; Embase; and SPORTDiscus) were screened. Three studies, including 103 participants diagnosed with OA, met the inclusion criteria, and all pointed out improved sleep quality. The methodological quality was classified as having ‘good’ (≥7), in two studies, and one study was classified as having a ‘fair’ methodological quality. The risk of bias was high in two studies, and in other some concerns was evidenced. Conclusion: Despite the modality, physical exercise improves sleep quality in individuals with OA. But it is necessary caution in the interpretation of the presented findings, and randomized clinical trials would be welcome.
